To ill whom it may Concern:

' rB'eit knownrthat we, An'ron' Conmand' 'Hnnnr L. :Parnrsn, citizens of the United States, res ding at. Los 'Angele's, in .the

county of Los Angeles and Stateof Galifornia, have Qinven'ted'jcertain new and useful Improvements in. Suction-Founders for:

washing Machines, of which the following is a specification. 1 This invention relates to suction pounders for. washing. machines, and belongs particu--- for working them up-and down. The up- Ward movement creates a partial vacuum;

and the wet'fabrie-Within the tub istempo-E fluid being" by such inovements correspond- I .i'ng .H, and, attention'is herecalled-to the rarily held to the poundercylinder byat-i :mospheric pressure, and is released b the;

downward movement, the; fabric an then;

inglyl; agitated.

The ob ect of this invention is the produc .tion of'a suctionpounder comprising parts,

of special construction and arrangement with. relation to each other, whereby 'it is,

believed the soiled articles of clothing of" the like, are rapidly raised and lowered with very little danger of being torn, and

the power necessary to operate the pounder cylinder is much reduced by reason of .the. fact. that the. partial vacuum is effectively created very-quickly, and is .as quickly and thoroughlybroken. It is thought that if the partial 'vacuumis quickly broken and the fabric at once'released, the probability is in-' creased that it will be taken in a difierent place by 'the nextupward movement. That is to say, a different portioinof the fabric will be held to the pounder cylinder as it is raised, and allportions thereof opened andexposed to the c eansing fiuid. The construct-ion and arrangement 0 parts comprising this invention, with the preferred means for operating the same are.

illustrated in the accompanying drawings, of which I Figure 1 represents an elevation partly in vertical. section showing all the parts in their relative positions. Fig. 2 is a view from below, with a portion of the perforated bottom broken away todisclose internal parts.

Throughout the drawings and description, the same letter is employed to refer to the same part..

ports by means of the pivo-t'pin a, the rocker arm B, that.- is attached toand'opeiated by Pins C so and ciprojcot from the ends of the rockeif 1 arm, and engage the taperin r orifices D and f the .upwardly-projecting handle 72 .tl in the ,piston rods E ancle, of the two pounder cylinders .F and f.

As the COIlStlllCtlQll' of both washers or ?.5

pounder cylinders F and is tl'ie'same, the

following description of one will apply to both. The piston rod E of pounderpylinder F, passes downwardly through the tubular casino; G, and a coil spring 7 encircles the red E within the casingzG. One end of the spring is attached to the rodand the other end to the inside of the casing, so that when" the rod is depressed the spring is corn pressed. and, the'rod is raised by the reaC- 7.5

-t-ion of the spring.

'T c slng- G s o1ne'd.to the conical casfact thatthe lower edge 11 of -the conical casing projects downwardly beyond the referred to. The bottom of the cylinder is 35 closed by the perforated plate K. iVithin I the p'oun'der cylinder F, and arranged to operate "up and down above the perforated plate K, is the plunger-or piston k, joined to .thepiston rod E by the braces L. .Imme 9e diately above the piston and 'norniallyresting upon it, is the valve plate M, through which the piston rod E passes movably. and the rod is connectedwith the center 'of the piston Z1. It will be understood, therefore,

that the piston rod E is attached to the piston 7.". at its middle point, and, also, rod E is connected 'withthe. piston k by braces L as set forth. The valve plate M normally closes the openings m in the piston b. There 10o mav be any desired number of such openings. v

l'n theoperation of this invention, the plston rod E is forced downwardly by rocking the arm 13- by means of handle I). In Fig. 1

it will-be observed, that as the handle I) is moved into its vertical position one of the pistons creates suction as it rises. Letit be assumed that the poundcr; cylinders were placed in a tub containing water and clothes f to be washed. The suction holds 'ja portion of the clothes to the perforated bottom of lateneease a'z',191s.

the pounder cylinder while the handle is brought 1nt0 its vertical position. N ow, the

operator haying by suction .a snitablejhold 1 upon the clothes and the handle vertical, moves the pounders and the'clinging clothes up and down in the water, materially aiding the cleansing operation. Now, when the piston is israised, it. sucks thewater through that p01 ion of the clothes held by suction against the perforated plate K, and, when the pistonnioves downagain, the dirty water just 'i'nentioned as drawn through the clothest'passes upwardly through the holes m in the piston, and is prevented from re turning by the valve plate M. As the pis-' orifices J are beneath the overhanging edge,

IL, of the conical portion H of the casing, and, those orifices are in that manner gua'rd ed against the splashing hack of the water through them, as the pounder cylinders are agitated. After the piston rod E has been depressed, it is allowed-to rise quickly under the force of the spring 9, and a partial vacuum .is formed within the cylinder, by the agency ofwhich the clothes are held to the perforated bottom plate K, in the usual manner, and vthe water sucked through the clothes. As -'soon as the piston starts down, the valve plate M'lifts and instantly breaks the vacuum, and releases the clothes, which are moved more or less by the general disturbance, so that the device tends to operate ,upon a new portion of the clothes at each stroke.

casings closed at the bottom, the bottoms of the casings being perforated, of mcansconstructed and arranged to connect the casings rigidly together, pistons provided with valves and arranged in the casinvs and hav ing rods entending upwardly through the topsof the/casings, and a handle extending upwardly and pivotally connected with the said rods and with the said casing-connecting means whereby said handle may be vibratedback and forth through its vertical pcsition to operate said pistons. 4

In a suction pounder for washing inachines, the combination with-a plurality of casings having conie-al'tops and fiat bottoms, said casings having circular seriesof holes near thetop and the tops of the casings projecting downwardly and outwardly over said holes, the bottoms of the casings being perforated, of means constructed and arranged to connect the casings rigidly toget-her, pistons provided with valves and arranged in the casings, said pistons having rods passing upwardly through the tops of the casings, and .a handle extending up wardly and .pivotally connected with the said rods and with the said'casing-connecting means whereby said handle may be vibrated back and forth through its vertical position to operate the pistons.

In testimony whereof we affix our signa-- 'tures inxpresence of two witnesses.
